Author: trasz Date: Tue Feb 19 11:07:02 2019 New Revision: 344276 URL: https://svnweb.freebsd.org/changeset/base/344276 Log: Bump the default kern.rpc.gss.client_max from 128 to 1024. The old value resulted in bad performance, with high kernel and gssd(8) load, with more than ~64 clients; it also triggered crashes, which are to be fixed by a different patch.
